Application April 22, 1949, Serial No. 89,079

This invention relates to a feeder pail and is particularly useful as acalf feeder pail, and for like purposes.

An object-of the present invention is to provide a feeder pail which maybe formed of thinner metal than is normally used while providing greatstrength at the point where the nipple is attached and where blows areusually applied to the pail by the calf in butting the pail. Yet anotherobject is to provide a structure in which the nipple is so attached thatthe pail is drained to the very bottom, while at the same time providinga buffer about the area" to which the nipple is attached. A stillfurther object is to provide a feeder pail in which soldering iseliminated, while at'the same time providing an innerlocked, welded,grooved ferrule plate which provides a grip for the end of the nipple.Other specific objects and advantages will appear as the specificationproceeds.

The invention is illustrated in a specific embodiment, by theaccompanying drawing, in which- Figure 1 is a perspective view of afeeder pail embodying my invention;

Fig. 2, an enlarged broken sectional view, the section being taken asindicated at line 2 of Fig. l; and

Fig. 8, a perspective view of the interior of the feeder pail and of theinner side of the ferrule plate, the parts being shown in detachedrelation.

In the illustration given, I designates a pail which may be of anysuitable construction and which may be provided with a bail I I. Thelower portion of the pail is pressed inwardly, as indicated in Figs. 1and 3, to provide an upper shoulder I2. The indented portion of the pailis provided with an aperture I3 and, preferably, the edges of the metalabout the aperture are turned outwardly to form a rim I I, as shown moreclearly in Fig. 2.

I provide an anchor or ferrule plate I5 with a shoulder IS on the innerside thereof, as shown more clearly in Fig. 3, and of the contourillustrated in Fig. 3, so that when the plate I5 is applied to theindented portion of the pail, the shoulder I6 fits against the shoulderI2 provided by the pail, and the upper apron portion I! of the plateprovides a guard lying against a wide portion of the pail thereabove.Thus, any pressure exerted against the plate I5 is distributed over arelatively wide area of the pail metal.

The ferrule or anchor plate I5 is preferably provided with a groovedopening I8 aligned with the opening I3 of the pail I0, and the innerportion of the plate is provided with a grooved par-- 4 Claims. (Cl.285-30) tion I9 adapted to receive the rim portion I4 of The plate I5 ispreferably secured to the pail- II] by electric spot welding and byrolling the rim 54 within the groove I9 of the plate I5. The spotwelding may be at the points 23, or at any other selected points.

In the construction of the pail, I prefer first to form the indentation,as above described, with the shoulder I2 and to form the opening I3 withthe outwardly spun rim I4. The plate I5, which has been formed in theshape illustrated best in Fig. 3, is then placed in position with theshoulder I6 engaging the shoulder I2 of the pail, and the plate is thenspot welded as already described. The nipple 20 is next drawn intoposition from the inside so that the lower point of the nipple isaligned with the bottom of the pail, as shown best in Fig. 2.

In the operation, the pail may be filled with milk and suspended in aposition so that the calf, etc. may suck upon the nipple and receive asupply of milk. While feeding, the calf repeatedly butts its headagainst the pail and the force here is taken by the anchor or ferruleplate I5, so that the stress is distributed over a wide area of themetal. At the same time, there is no projecting metal tube or other partwhich will injure the head of the calf. When the nipple is removed forcleaning, it may be readily withdrawn from the inside of the pail.

The new structure is extremely sturdy, while at the same time enablingthinner metal to be used in the fabrication of the pail. At the sametime, an extremely sturdy and reinforcing structure is provided aboutthe nipple 20 by the ferrule or anchor plate. Liquid may be drained fromthe very bottom of the pail and quick substitution of nipples can beeffected without the use of any instrument or without requiring anythingmore than the withdrawal or insertion from the inside. If desired, thenipple may be equipped with the usual check valve.

While in the foregoing specification I have set forth a specificstructure in considerable detail for the purpose of illustrating oneembodiment of the invention, it will be understood that such details ofstructure may be varied widely by those skilled in the art withoutdeparting. from the spirit of my invention.

Iclaim:

1. A feeder pail having a lower portion thereof adjacent the bottomindented and having an aperture extending therethrough, said indentationproviding an external horizontal shoulder, an anchor plate having aportion thereof received within said indentation and secured to saidpail about said indentation, said anchor plate having a shoulderabutting the lower side of said pail shoulder, said plate having agroovedequipped passage therethrough aligned with the opening in saidpail, and a resilient nipple having an inner end engaging a groove ofsaid plate.

2. A feeder pail, comprising a pail having alower portion thereof on oneside indented to provide a shoulder and having an opening through saidindented portion, a ferrule plate having a shoulder interlockinglyengaging the underside of the shoulder of said pail and having an apronextending beyond said shoulder, said ferrule plate having agroove-equipped passage therethrough aligned with the opening in saidpail, and a resilient nipple having an inner portion engaging a grooveof said plate.

3. A feeder pail, comprising a metal pail having the lower edge portionthereof adjacent the bottom indented and provided with an openingaligned with the bottom of the-pail, the metal about said opening beingspun outwardly, a ferruleplate having a groove-equipped passage alignedwith the opening of said pail and having an inner groove thereofreceiving the outwardly spun portion of said pail, said plate having aportion thereof snugly received within said indentation andoutwardly-extending portions extending beyond said indentation, saidplate having a portion thereof confined by said recess against upwardmovement, said plate being welded to said pail, and a resilient nipplehaving an inner portion gripping the grooves of said plate and havingthe lower portion of said nipple substantially aligned with the innerbottom portion of said pail.

v4. A feeder pail, comprising a relatively thin metal pail having abottom portion thereof indented and having an opening extending throughsaid indentation, a ferrule plate welded to said pail and having ashoulder portion thereof interlockingly engaging a shoulder provided bythe indentation in said pail, said plate having a ridgeequipped openingtherethrough aligned with the opening in said pail and having a taperingapron portion extending upwardly in contact with the side wall of thepail, and a resilient nipple having an inner end gripping a ridge ofsaid ferrule plate.
